To allwhom it may concern Be it known that I, AUGUST BUoHoL'rz, a subject of the-German .Emperor, and resident of Delmenhorst i. Oldenburg, Germany, have invented certain new and useful Improvements in Methods of and Apparatus for Manufacturing Striped Linoleum on a Calender, of which the following is a statement.

Generally striped linoleum is givena grain resembling ears of corn by the linoleum compound being fed from between partitions before it passes between the press rollers.

The object of the present invention is to give such striped linoleum a rectilinear, uniform grain in place of such earshaped grain.

This object is obtained by the linoleum compound being rammed at both sides of the partitions before it passes between the press rollers. The grain is then produced under cooperation of such ramming with a greater regularity in the linoleum compound. which is no more left entirely to itself, and the grain thus obtained is of a rectilinear, more uniform character.

For carrying out the method here described an arrangement is employed, which has been exemplified in the accompanying drawing, in which Figure 1 1s a view of a part of a linoleum making machine showing my invention applied thereto, parts being in section and parts in side elevation; and Fig. 2 1s atransverse sectional view of the same.

Above the rollers a, between which the jute backing Z) travels, are disposed dividing bars or partitions 0. Parallel to the calender rollers a is journaled a shaft d which is driven in a suitable manner'from the cal ender engine. 011 this shaft d are keyed eccentrics 6 connected to operate rammers f disposed at both sides of the partitions c and guided in slots in the latter. The partitions o are secured in spaced relation by means of lock nuts on the threaded rod g and may be laterally displaced and set at will.

The differently colored masses of linoleum composition are fed from the spaces between the thin partitions. to and through the calender. During thefeeding of the composition the rammers f compress the composition at the edges of the stripes so that 2. rectilinear grain is produced when the adja- Spec i fication of Letters Pate'iit.

Iclaimz- 1. ,The method of manufacturing striped linoleum which comprises calendering sep arate masses of linoleum composition on a backing to produce a sheet of linoleum having distinct stripes, and compressing the edges of said separate masses before the masses are calendered wherebya striped linoleum'jhaving a uniform rectilinear grain is produced.

2. In an apparatus for manufacturing striped linoleum, the combination of a calender, a partition separating the masses of linoleum composition fed to said calender, and means for ramming the composition at the sides of the partition before it passes to the calender.

3. In an apparatus for making striped linoleum, the combination of a calender, means for feeding to said calender separate masses of linoleum composition to produce distinctstripes in the linoleum, and means for operating on the meeting edges of the stripes so as to produce a rectilinear uniform grain in the linoleum.

4. In an apparatus for making striped linoleum, the combination of a calender, a plurality of spaced partitions forming compartments to receive separate masses of linoleum composition to be fed to the calender, and means for ramming the linoleum composition at both sidesof the partitions before the composition passes to the calender whereby a rectilinear uniform grain is produced in the linoleum.

- 5. In an apparatus for making striped linoleum, the combination of a calender, a plu rality of spaced partitions forming compartments to receive separate masses of linoleum composition to be fed to the calender, and devices movable along the opposite sides of each partition capable of operating on the composition at both sides of the. partitions before said composition passes to the calender, whereby a linoleum having a uniform rectilinear. grain will be produced.

,6. In an apparatus for making striped lino i leum composition, means mounted on opposite sides of each partition and adapted to extend into the space between said rollers and capable'of ramming the linoleum composition at the sides of the partitions beforerit passes through the calender rollers, and means for operating said ramming means;

7. In an apparatus for making striped linoleum, the combination of a pair of calender rollers, a plurality of spaced thin partitions above said rollers and having parts extending into the space between the rollers, said partitions forming compartments for masses of linoleum composition, means'for compressing the composition at each side of each partition before it passes through'the calender rollers, and means for reciprocating said compressing means.

8. In an apparatus for making striped linoleum, the combination ofa pair of calender rollers, a plurality of spaced adjustable thin partitions above the rollers and having parts extending into the space therebetween, said partitions providing separate compartments for masses of linoleum com- 2 position, and means for ramming the linoleum composition at both sides of each partition before the composition passes through the rollers, said ramming means comprising a ramming device mounted on each side of 3 each partition, the partitions having slots to guide the ramming devices thereon, a shaft above the rollers and extending transversely of the partitions, eccentrics rotatable with said shaft, and rods connecting said eccentrics with said ramming devices whereby a reciprocating motion is imparted to the latter when the shaft rotates.

In testimony whereof I have hereunto set my signature in the presence of two sub 4 scribing witnesses.
